USN-5791-2: Linux kernel (Azure) vulnerabilities It was discovered that a race condition existed in the Android Binder IPC subsystem in the Linux kernel, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-20421) David Leadbeater discovered that the netfilter IRC protocol tracking implementation in the Linux Kernel incorrectly handled certain message payloads in some situations. A remote attacker could possibly use this to cause a denial of service or bypass firewall filtering. (CVE-2022-2663) It was discovered that the Intel 740 frame buffer driver in the Linux kernel contained a divide by zero vulnerability. A local attacker could use this to cause a denial of service (system crash). (CVE-2022-3061) It was discovered that the sound subsystem in the Linux kernel contained a race condition in some [ more… ]

USN-5792-2: Linux kernel vulnerabilities Mingwei Zhang discovered that the KVM implementation for AMD processors in the Linux kernel did not properly handle cache coherency with Secure Encrypted Virtualization (SEV). A local attacker could possibly use this to cause a denial of service (host system crash). (CVE-2022-0171) It was discovered that a race condition existed in the Android Binder IPC subsystem in the Linux kernel, leading to a use-after-free vulnerability.

USN-5797-1: WebKitGTK vulnerabilities Several security issues were discovered in the WebKitGTK Web and JavaScript engines. If a user were tricked into viewing a malicious website, a remote attacker could exploit a variety of issues related to web browser security, including cross-site scripting attacks, denial of service attacks, and arbitrary code execution.

USN-5796-1: w3m vulnerability It was discovered that w3m incorrectly handled certain HTML files. A remote attacker could use this issue to cause w3m to crash, resulting in a denial of service, or possibly execute arbitrary code. Source: USN-5796-1: w3m vulnerability

USN-5795-1: Net-SNMP vulnerabilities It was discovered that Net-SNMP incorrectly handled certain requests. A remote attacker could possibly use these issues to cause Net-SNMP to crash, resulting in a denial of service. Source: USN-5795-1: Net-SNMP vulnerabilities
